Application filed February 14, 1916. i Serial No. 78,222.

To all whom it may concern:

Be it known that I, CHRISTOPHER F. CODA, a citizen of the United States of America, residinga-t Detroit, inthe county of Wayne and State of Michigan, have invented certain new and useful Improvements in Combined Ranges and Gas-Stoves, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a combined range and gas stove, and more particularly to a combined range and gas stove of the type in which the same oven is adapted to be heated either by burning solid fuel or by heat generated from a gas burner.

Among the objects of the invention are to provide a combined range of the character referred to, in which the oven will have a maximum of efliciency when heated by either solid or gaseous fuel, and in which the stove can be completely converted from one type to the other by the simple adjustment of a single lever or the like.

The invention. resides in the provision of an outlet from the oven for the products of combustion, when the gas burner is in use, and in the novel manner of automatically controlling this opening; in the provision of improved means for adjusting the gas burner and its shield into inoperative position when the oven is to be heated by burning coal or other solid fuel; in the mechanism for automatically closing both the air inlet and outlet openings when the burner and shield are moved into inoperativeposition, and for automatically opening the inlet and outlet connection when the gas burner and shield are returned to operative position; in the particular mounting and connections for the burner and shield; and further, in such features of construction and arrangements and combinations of parts as will more fully hereinafter appear.

In the drawings,-

Figure 1 is a sectional front elevation;

Fig. 2 is a side elevation partly in section;

Fig. 8 is a sectional plan view on the lines g of Fig-l;

Fig. et is a perspective view .of the shield and burner partly adjusted to inoperative position.

e In he particular embodiment of my invention shown in the drawings, A designates the combination range, which is provided pipe opening J as the products of combuswith the fire-box B and at'the top has the usual cover C for coal, and may or may not be provided with additional burners I) for gas. The oven E is, however, adapted to be heated either by solid fuel burned in the fire-box B, or by means of a gas burner F located at the lower part of the oven. It is usual to provide the oven burner with a baflie plate or shield G. lVhen, however,

the oven is to be heated from the fire-box B, it is desirable to adjust the gas burner and the shield to an inoperative position at the rear of the oven, as shown in dotted lines in Fig. 2. I

The mounting of the shield and burner and the'mechanism for adjusting them to" and from inoperative position are preferably so arranged that the shield and burner can be adjusted to either position by the operation of a lever H, which lever is accessible from the exterior of the stove. l/Vhen, however, the oven E is to be heated by gas, it is necessary to supply air to the burner F to support combustion and to also provide means for permitting the escape of the products of combustion out of the" oven. For this purpose an air inlet opening I is employed below the plane of the burner, and. an outlet opening J also provided which permits the products of combnstion to pass into the elongated chamber J, which in turn opens into the main flue chamber J From the latter chamber the burnt gases pass out through the same smoke tion from the fire-box B.

In order to avoid counter-drafts through these openings when the oven is heated by solid fuel, I provide means for closing the openings I and J, particularly the latter, and the present invention contemplates an arrangement of parts whereby the opening J will be automatically closed when the lever H is adjusted to move the shield and burner into inoperative position. As shown in Fig. 1, the opening J is controlled by a damper L pivoted at L and connected to a rock arm L This rock-arm has an offset portion L projecting into the path of the shield when the latter is being adjusted to inoperative position. The weight of the" arm L is su-fiicient to normally hold the damperin open position, but whenever the burner and shield are swung back to inoperative position, the edge M of the main portion M of the shield will, by rocking the arm L forcethe damper to closed position, and so hold it until the shield and burner are again adjusted to operative position, when the weight of the rock-arm will automatically rock the damper L about its.

pivot so as to uncover the outlet opening J.

The air inlet opening I is also automatically controlled by movement of the shield into and out of operative position. In the particular structure shown, the air inlet opening is controlled by a pivoted damper N normally held closed by a weighted arm N. To open this damper the burner is provided with a depending lug N When the burner and shield are returned to operative position, this lug, owing to the greaterweight of the burner and shield, will force the damper open against the weight of the arm N. burner and shield to inoperative position, the weight of the arm will cause the damper to automatically close the inlet opening I.

The construction of the shield and burner and the mounting for the same is as follows: The burner F is preferably provided with a diagonal portion F, which at the rear outer corner of the oven, terminates in an integral section F projecting axially through an opening E in the oven wall. This section F is free to rotate in the opening E as a bearing and forms one of the pivots about which the burner and shield are rocked. Near the inner rear corner of the main section M the shield G is provided with the other pivot G. The other section I 2 of the shield is attached to the main section M by suitable off-set hinges M and preferably the central portions of the meet ing edges of the sections are offset at O and 0 where the burner F is located as shown in Fig. t.

At its front end the section M is supported by a roller P, this section when the burner and shield are moved to inoperative position, automatically folding back against the section I Means are also provided for compelling the section M to automatically open when the burner is rocked down to operative position. In the particular structure shown, I employ an arm R pivoted at its upper end to the section M and provided at its lower end with a roller S, which roller when the burner and section M are rocked downward will engage the fioor of the oven I rocked into and out of operative position. By

the same adjustment of the lever the shield will be automatically folded or unfolded and i moved into or out of operative position, and

However, upon movement of the simultaneously the air inlet and outlet openings closed or opened accordingly as the oven is desired for gas or solid fuel.

V What I claim as my invention is 1. In a combination range, the combination with an oven, a burner therein, of a shield for said burner, comprising front and rear sections hinged together, the rear sec tion being connected to the burner so as to be moved therewith to inoperative position, the front section having a roller engaging the fioorof the oven for supporting the shield when moved to operative position, and an arm pivoted to' the front sectionand having a roller which will'engage the floor of the oven when the burner and shield are being returned to operative position and force the front section to open out awa I sections hinged together, the rear section being connected to the burner so as to be moved therewith to inoperative position, the front section having a member engaging the floor of the oven for supporting the shield when moved to operative position, and an arm pivoted to the front section engageable with the floor of the oven when the burner and shield are being returned to operative position to force the front section to open out away from the rear section.

3. In a combination range, the combination with an ven, a burner therein, a shield" for said burner comprising front andrear sections hinged together, the rear section being connected to the burner so as to be .moved therewith to inoperative position, the

front section having a member engageable with the floor of the oven for supporting the shield in operative position, and an arm pivoted to one of said sections engageable with the floor of the oven during adjustment .of the burner and shield to operative position to force the front section to open out away from the rear section.

4. In a combination range, the combination with an oven, of a burner therein, a shield for said burner comprising front and rear sections hingedly connected, the rear section being secured to the burner so as to be moved therewith to inoperative position, the front section having a roller engageable with the oven floor to support the shield in its operative position, and an arm pivoted to one of said sections having a roller engageable with the floor of'the oven during adjustment of the burner and shield to operative position to force the front section to open out away from the rear section.

' 5. In a combination range,the combination with an oven, of a burner therein having a ioo pivotal portiontransverse of the oven at the rear thereof and having a parallel portion in the front section being correspondingly cut away at its rear edge, said burner being secured to the rear section and having its front transverse portion engaged with said projection, and means for adjusting said burner and shield to an inoperative position at the 10' rear of the oven.
